Utility to search and download Sentinel-1 Imagery
Project description
sentinelsat
============
.. image:: https://badge.fury.io/py/sentinelsat.svg
:target: http://badge.fury.io/py/sentinelsat
Utility pack to search and download Sentinel-1 imagery from `ESA SciHub <https://scihub.esa.int/>`_.
Installation
============
Sentinelsat depends on `homura <https://github.com/shichao-an/homura>`_, which depends on `PycURL <http://pycurl.sourceforge.net/>`_, so you need to install some dependencies on your system.
Ubuntu
.. code-block:: console
sudo apt-get install build-essential libcurl4-openssl-dev python-dev python-pip
Fedora
.. code-block:: console
sudo yum groupinstall "Development Tools"
sudo yum install libcurl libcurl-devel python-devel python-pip
Windows
The easiest way to install pycurl is to use one of the `pycurl wheels <http://www.lfd.uci.edu/~gohlke/pythonlibs/#pycurl>`_ provided by Christoph Gohlke.
.. code-block:: console
pip install pycurl.whl
Alternatively if you are using `Conda <http://conda.pydata.org/docs/>`_ you can do
.. code-block:: console
conda install pycurl
Then install ``sentinelsat``:
.. code-block:: console
pip install sentinelsat
Usage
=====
Sentinelsat provides a Python Library and a Command Line Interface to search and
download Sentinel-1 products.
Command Line Interface
----------------------
Search
^^^^^^
.. code-block:: console
sentinel search [OPTIONS] <user> <password> <geojson>
Search for Sentinel-1 products and, optionally, download all the results.
Beyond your scihub username and password, you must pass a geojson file
containing the polygon of the area that you want to search in. If you
don't specify the start and end dates, it will search products published in the last 24
hours.
Options:
-s, --start TEXT Start date of the query in the format YYYYMMDD.
-e, --end TEXT End date of the query in the format YYYYMMDD.
-d, --download Download all results of the query.
-c, --check Verify the MD5 checksum and write corrupt product ids to a
textfile.
-f, --footprints Create geojson file with footprints of the query result.
-p, --path PATH Set the path where the files will be saved.
-q, --query TEXT Extra search keywords you want to use in the query.
Separate keywords with comma.
Example: 'producttype=GRD,polarisationmode=HH'.
-u, --url TEXT Define another API URL. Default URL is
'https://scihub.esa.int/apihub/'.
Download
^^^^^^^^
.. code-block:: console
sentinel download [OPTIONS] <user> <password> <productid>
Download a single Sentinel-1 Product. Provide your scihub username and password and
the id of the product you want to download.
Options:
-p, --path PATH Set the path where the file will be saved.
-c, --check Verify the MD5 checksum and write corrupt product ids to a
textfile.
-u, --url TEXT Define another API URL. Default URL is
'https://scihub.esa.int/apihub/'.
Python Library
--------------
Connect to the API:
.. code-block:: python
from sentinelsat.sentinel import SentinelAPI
api = SentinelAPI('user', 'password')
If you need to search or download data produced before November 16th, 2015, you must initialize `SentinelAPI` with the `api_url` parameter, setting it to use `https://scihub.esa.int/dhus`.
.. code-block:: python
api = SentinelAPI('user', 'password', 'https://scihub.esa.int/dhus')
If you know the id of the product you want to download, you can download it by using:
.. code-block:: python
api.download(<product_id>)
It is possible to hide the progress report, disable resume and auto_retry, and
pass any other keyword argument understood by the underlying homura library, e.g.:
.. code-block:: python
api.download(<product_id>, show_progress=False, max_rst_retries=2)
You can also use the id to get information about the product, including id, title, size, footprint and download url:
.. code-block:: python
api.get_product_info(<product_id>)
You can search products by specifying the coordinates of the area and a date interval:
.. code-block:: python
api.query('0 0,1 1,0 1,0 0', '20150531', '20150612')
You can query by using date or datetime objects too.
.. code-block:: python
api.query('0 0,1 1,0 1,0 0', datetime(2015, 5, 31, 12, 5), date(2015, 6, 12))
If you don't specify the start and end dates, it will query in the last 24 hours.
Beyond area and date parameters, you can use any search keywords accepted by the scihub API, for example:
.. code-block:: python
api.query('0 0,1 1,0 1,0 0', producttype='SLC')
See the `SciHub User Guide <https://scihub.esa.int/twiki/do/view/SciHubUserGuide/3FullTextSearch#Search_Keywords>`_
for all the Search Keywords.
To download all the results of your query, use:
.. code-block:: python
api.download_all()
To get a geojson FeatureCollection containing the footprints and metadata for the search results of the query, use:
.. code-block:: python
api.get_footprints()
The download from https://scihub.esa.int will fail if the server certificate
cannot be verified because no default CA bundle is defined, as on Windows, or
when the CA bundle is outdated. In most cases the easiest solution is to
install or update `certifi <https://pypi.python.org/pypi/certifi>`_:
.. code-block:: console
pip install -U certifi
You can also override the the path setting to the PEM file of the CA bundle using
the ``pass_through_opts`` keyword argument when calling ``api.download()`` or
``api.download_all()``:
.. code-block:: python
from pycurl import CAINFO
api.download_all(pass_through_opts={CAINFO: 'path/to/my/cacert.pem'})
